How to refresh DataTable with server side processing and scroller plugin

Mike 2015

I was tried to use these approaches:
1. Using api().draw(false) function, but it resets scroll offset
2. Using api().ajax.reload(null, false). It resets scroll offset too.
3. Using dataTable._fnDraw() function. It doesn't work too. There is a bug when you are trying a bit scroll and after _fnDraw() call it scrolls to previous position. When you are scrolling a lot - it works well.

My TypeScript code:

var dataTableOptions = {
                serverSide: true,
                ordering: true,
                searching: true,
                columns: [
                    { "data": "id" },
                    { "data": "workflowId" },
                    { "data": "discovery" },
                    { "data": "title" },
                    { "data": "createdBy" },
                    { "data": "createDate" },
                    { "data": "status" }
                ],
                ajax: (data, callback, settings) => {
  // server side service call
                },
                dom: 'rtiS',
                scrollY: 400,
                scroller: {
                    rowHeight: 35,
                    loadingIndicator: true
                },
                initComplete: function () {
                    forceRefresh = _.throttle(() => {
                        //this.api().ajax.reload(false);
                        this._fnDraw();
                    }, 1000);
                    setInterval(() => {
                        forceRefresh();
                    }, 5000);
                }
            }
